Obama, through no fault of his own, might have lost his U.S. citizenship — either through residency requirements or by the fact that he was legally adopted by an Indoneasian.

If born in USA, all other issues are irrelevant. He's a US citizen forever, unless he formally renounces his citizenship.

If born elsewhere, which is possible though not likely, he might still be a "native-born citizen," although some of these residency requirements and other issues might come into play.

It is not possible to "accidentally" lose one's US citizenship. A parent cannot renounce citizenship for a child. Traveling on a foreign passport or even becoming a citizen of another country under their laws does not void citizenship. Our laws do not care what other countries have to say about citizenship.

The only way to lose American citizenship is to formally and in writing renounce it following the prescribed procedures, as an adult. No other way.
